8/13/2023 0 Comments Water conveyance pipe naterialHistorically, seamless pipe was regarded as withstanding pressure better than other types, and was often more available than welded pipe.Īdvances since the 1970s, in materials, process control, and non-destructive testing, allow correctly specified welded pipe to replace seamless in many applications. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Seamless (SMLS) pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell in a process called rotary piercing. Ductile iron pipes are generally manufactured in such a fashion. Centrifugal casting of hot alloyed metal is one of the most prominent process. There are three processes for metallic pipe manufacture. The Pyramid of Sahure, completed around the 25th century BC, included a temple with an elaborate drainage system including more than 380 m (1,247 ft) of copper piping. The first known use of pipes was in Ancient Egypt. Handrails, scaffolding, and support structures are often constructed from structural pipe, especially in an industrial environment. The construction of high pressure storage vessels (note that large pressure vessels are constructed from plate, not pipe owing to their wall thickness and size).Īdditionally, pipes are used for many purposes that do not involve conveying fluid.Delivery of bulk solids, in a food or process plant from one point to another point in the process.Delivery of fluids, either gaseous or liquid, in a process plant from one point to another point in the process.High-temperature or high-pressure manufacturing processes. ![]()
